Patent products, The airport runway dedicated repair material) For the west airport pavement damage repair

Airport runway dedicated to repair the runway dedicated repair material airport runway airport concrete pavement disease treatment materials common diseases are as follows: 1, the pavement blow up deformation damage - — Uneven deformation, forming wave, beat, serious decline, pavement roughness of subgrade soil structure damage. 2, uneven pavement so - — 12 - in pavement concrete casting 24 hours a day, between encountered some cool wind, caused by the factors such as the concrete surface strength, when there is no heat preservation measures or not timely, kerf width will appear in a few hours so 3, 3. 1 surface crack - — Statue of concrete pavement appeared shrinkage crack and shrinkage crack is the common defects in airport pavement, belongs to the surface crack. 3. 2 temperature crack - — Temperature cracks occurred in early is not yet in the process of solidification of concrete with time change, the way of the construction in winter and summer, more serious. 3. 3 reflection crack - — Crack is a kind of fatigue damage of radiation. Under the effect of the periodic bending tensile stress, the cement concrete pavement will produce fatigue damage, produce reflection crack. 4 4 of link failure. 1 joint fracture - — Joint fracture including longitudinal seam rupture and transverse crack is broken two types. Longitudinal seam fracture is a crack on the surface of the pavement and the pavement itself falling wedge joint together. Cross stitch seams transverse cracks or crush in. 4. 2 joint arch rise - — Arch rise is TongMianBan is blocked on surface of the thermal expansion, one on either side of the seam panel suddenly upward arching phenomenon. 4. 3 joint pumping mud - — Is aircraft wheel load through the seam, the seam in the phenomenon of spitting out the thin mud. 4. Four juncture wrong station - — Is a joint on both sides of the panel, the phenomenon of the vertical relative displacement. 4. 5 seams out side out Angle - — Is seam edges, the phenomenon of the small pieces of concrete spalling. 4. Six Angle accidentally break - — At the Angle of accidentally appear from voids to cracks at the ends of the distance is less than half of the plate length, known as the Angle of fracture. As a first step, first will depart airport pavement diseases in pit slot in the second step, will pit slot edge properly dealing with the third step, stir - patent products - - - - - - Airport pavement concrete defect repair materials for repairing the fourth step, special repair material after construction, in a timely manner, timely maintenance of light! Fifth, then coated - patent products Airport pavement special protection seam an agent
